WHAT IS PLC in HVAC?
By Christopher Davis •
HVAC system designed by engineer completely depends upon temperature or humidity requirement in the plant and customer's requirement. Programmable Logic Controller (PLC) used to maintain automation in the system. PLC contains IO modules with interfaces, programming ports, memory.
.
Keeping this in view, what is a HVAC control module?
An AC/heater control module is a computer that controls and automates the operation of the heating, ventilation, and air conditioning systems (HVAC).
Secondly, what is the difference between DDC and PLC? A DDC ( Direct Digital Controller ) is similar in function to a small PLC . A PLC ( Programmable Logic Controller ) is a much more versatile control system. It's capable of handling digital and analog inputs/outputs and is used for control of complicated machinery, as well as entire process control systems.
One may also ask, what's the purpose of controls in an HVAC system?
HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state.
How does HVAC heating work?
Combustion gases are generated by the burners in your furnace and passed through a heat exchanger. Air from your home blows across the heat exchanger to be warmed. It is then blown through a system of ducts to distribute around your home. During warm seasons your heating system works with your central air conditioning.
